PREPARATION AND SETUP

Hose Attachment

Apeks recommends that you take your regulator to your authorised dealer for the installation of any accessory items, including instrumentation, medium pressure (MP) quick disconnect hoses, and alternative air source second stages. Your dealer can also answer any questions you may have pertaining to the information in this manual. If it is not possible to return your regulator and accessories to your Apeks / Aqualung Authorised Dealer, you may install the accessories yourself carefully performing the steps in the following procedure.

Hose fitting operation for lightweight second stages

It is always recommended that your dealer assembles your regulator with all your ancillary requirements. As this is not always possible please follow the following steps, to ensure correct fitment of the flight second stage. Your Apeks Flight regulator should be supplied with a lightweight hose fitted with the Tool Free Connection. If this is not the case, for example; when using Flight alternative air sources or Flight octopus second stages please follow the following steps:

Warning:

Do not overtighten or use tools to tighten the hose.

Damage may occur.

(2) Screw the hose nut on to the inlet fitting until it stops, ensuring the threads do not cross.

(1) Firstly ensure the hose nut is able to rotate freely without turning the hose.

Visually check the thread on the second stage inlet, removing any particles or debris. Do not use any grease or lubricants as the composite material does not require it.

(3) The nut will ratchet on the locking slide ring as the nut is screwed in, producing an audible clicking sound. This system prevents the hose from unscrewing and coming free.

Approximately 3 turns are all that are needed to tighten, which will produce aproximately

16-18 clicks of the ratchet.

Warning:Ensure that the hose nut screws up until it stops.

Do not over tighten with tools as this will not prevent leakage in unlikely event of damage.

Important: 1st Stage:

Warning:If a 2nd stage is not being used,

ALWAYS ensure a medium pressure relief valve is fitted.(Apeks part

No:AP0640).

Hose fitting operation for All First Stages.

WARNING: DO NOT connect medium pressure hoses (inflator hoses and second stage hoses) to high pressure (HP) ports.

This will cause medium pressure hoses to burst when pressurised, which can result in serious injury. High pressure ports are identified by the letters ‘HP’ on your regulator and are mainly used for instrumentation and air integrated computers.

1. Remove the port blanking plug from your first stage regulator using a 5mm Allen key.

Note: Care must be taken when using a spanner/ wrench when tightening the hose connections.

The spanner can score and damage the chrome plating finish of the first stage body around the port area.

2.Ensure the O-Ring is present and in good condition on the hose to be fitted. Screw the threaded end of the hose into the port, making sure that the thread is screwed in square to the port. Tighten to 46kg/cm (40ibs/ in)using an appropriate spanner.
